Issue ID 68387 68839 68840 70792 71952 75801 79411 80283 80428 80779 81188 Item Description CLI command controlport rst Using CLI command controlport rst -l on a 10G iSCSI port -l can lead to fatal PCI errors under heavy host I/O can lead to fatal PCI errors and a subsequent node reboot. User guide edits Need to remove references to the MENU Driven Application from the UG if it is deprecated. Menu Driven Application deprecated Need to update RMO 4.1 RN's to indicate the Menu Driven Application has been deprecated tunesys should not be run with a There is a problem with the chunklet moving algorithm used in the maxchunk value of more than 2 intra-node (tunenodech) phase of tunesys. This causes a high (default) chunklet move failure rate if the value of maxchunk (number of chunklets that can be moved in parallel) is set to greater than 2 (default). It is recommended that the value of maxchunk is left at its default for all tunesys runs. Remote Copy User Guide In this guide the maximum supported RCIP latency (delay times) is incorrect. Persistent Port fc failover/failback SLES host device-mapper detected fail paths On FC ports with a large number of attached hosts, failover/failback may not be sufficiently fast with the consequence that multipathing messages may be seen in host logs. Host multipathing may temporarily mark paths as failed but they are quickly re-instated. This behavior has been observed on Linux hosts (Redhat and SLES11) which have more stringent path validation algorithms. However, it is conceivable that it could also be observed on other host types depending on how heavily the interface is loaded. I/O fails when a persistent port event occurs with windows 2008 r2 sp1 on ucs with m81kr Cisco VIC HBA M81KR is not supported with 3.1.2 at this time. Solaris host loses paths in some failover/failback scenarios, in configurations involving a Brocade switch This problem is a defect on the Solaris host. The Brocade switch has a feature where it will consolidate events that happen in close succession into a single RSCN. The FC subsystem on Solaris does not handle this appropriately and therefore does not re-establish all the paths as it should. Impact: Assuming host multi-pathing is configured properly, if this problem occurs the customer may lose some IO paths, resulting in possible reduced performance until the failed paths are restored. Failed paths can be restored via controlport rst. Note that this problem only shows up with the combination of Brocade switch and a Solaris 11 host. A VV in an AO configuration may A VV which is split between tiers by Adaptive Optimization may occasionally display incorrect RAID incorrectly display RAID type and device type (SSD, FC, NL) type and device type information information for a secondary tier CPG. This is a display issue and does not affect the primary tier CPG from which new VV growth is taken. Error message that volume is locked Active volume removals will prevent periodic syncs starting for volumes within the same volume family. An error message will be returned indicating that the volume is locked. Once the removals have finished the next periodic sync will succeed. Periodic RC stalled during online upgrade from 3.1.1.MU1 to 3.1.2 During an online upgrade periodic remote copy groups may stop syncing. If this occurs, normal operation will resume as soon as the upgrade is completed (i.e. after the cli upgradesys -finish command has been entered). There is no need to stop periodic groups before the upgrade is carried out. Synchronous Remote Copy groups are unaffected. I/O to volumes in remote copy groups is unaffected. No manual intervention is required to Remote Copy groups or volumes before, during or after the upgrade. 16 HP 3PAR OS 3.1.2 GA Release Notes
